30
[Bitrate]:
The range for the preferred and alternate streams is
30~16384Kbps. Higher bitrate settings can generate
better image quality, but it occupies more bandwidth,
please adjust the setting according to your actual band
width.
Under the CBR setting, [Bitrate] is the encoding’s
constant bitrate.
Under VBR setting, [Bitrate] is the encoding’s variable
bitrate .
[Frame rate]:
Set the encoding frame rate per second. Under poor
network conditions the frame rate can be reduced to
control the encoding bitrate to make motion images
flow more smoothly.
[GOP]:
Adjustable between 1~200 (Preferred Stream), 1~200
(Alternate Stream). Smaller I-frame interval mean a
higher bitrate and better image quality. It is
recommended to set the I-frame interval above 25.
